conflicting devices?

[vlrbsf]

I use an eMachine with WinMe and I recently added a Brother MFC. I could not get it to work until I disconnected my Iomega CD-RW. Now I can only get my CD-RW to work if I unplug Brother. I am using USB2. I went to the Iomega website and downloaded the patch there but it did not change my problem. When I boot up with both devices connected I freeze at the Windows screen. I can't figure this out-need help!
